thanks for the reply guys,
as armonox said, HFS+ support has been around for a bit but writing and journaling don't go together.
time machine says journaling needs to be enabled to work, but fedora says journaling needs to be disabled to work. but i have heard a few
people mention using a samba share as a time machine backup; this is in direct contradiction to that first sentence. i was wondering if anyone had successfully done this, if so how?
